Electronic Power Assisted Steering System

Abstract

Electric power steering (EPS or EPAS) is designed to use an electric motor to minimize the effort by providing steering assist to the driver of a vehicle. Sensors detect he motion and torque of the steering column, and a computer module apples assistive torque via an electric motor coupled directly to either the steering gear or steering column. This allows varying amounts of assistance to be applied depending on driving conditions. The system provides engineers to shoehorn steering-gear response to variable-damping suspension systems achieving a perfect blend of ride, handling, and steering for each and every vehicle. This effect of global warming is becoming increasing apparent. As a result, we product engineers are being asked to develop products that are more friendly to the earth’s environment electric power (EPS) is such a product. By using power only when the steering wheel is turned by the driver, it consumes approximately one-twentieth the energy of conventional hydraulic power steering system and, as it does not contain any oil, it does not pollute the environment both when it is produced and discarded.
